Subject: plasma sphere

Post:
I have my large plasma sphere out for some upcoming Halloween demos. Kids
are amazed by this device. One asked why the glowing purple lines (between
the central electrode and the outer glass surface) always rise. I never
really noticed this before, so I examined the motion for a while and it
was true. I was and remain baffled.

So why do those line rise?
